Is international roaming in Argentina included for free with my European or North American SIM card?

¡No, ten cuidado! This is a common misconception and a major roaming trap. While Argentina is a popular destination, it is not part of the European Union or any North American domestic roaming agreements. Your 'Roam Like at Home' plan will not apply here. Most EU, UK, US, and Canadian carriers (like Vodafone, AT&T, Telus) will charge exorbitant 'Rest of World' international roaming rates, which can quickly lead to hundreds of dollars in unexpected bills. An Ecuador Abroad regional eSIM is a much smarter, more affordable choice.
